Two distinct uterine bodies are present. Within the left uterus, there is a single gestational sac containing two fetal poles - each accompanied by a yolk sac and each clearly surrounded by a separate amnion - the two amnions having not yet fused to form a single intertwin membrane.
Concordant size of the two embryos, each generating a gestational age of 8 weeks 3 days. In both, cardiac activity is demonstrated.
A corpus luteum is present on the left side - as expected, given that the pregnancy is in the left uterus.
